A lot of rookies' first casks are finished, and 80% are filtered. As for the filtering effect, i myself tried to raise three tigers and feed shrimp once a day. The whole filter is full of biochemical beads. It works, but it's a little hard to get another fish。

Filtration of the finished cask. There's a lot of options. Considering the cost and space utilization, i choose filtering。
However, the weight of the water stored is heavier if it is filtrated with ordinary spills, and this modification is relatively common. So we're thinking of designing a glass drop-in of a finished tank that uses the drop-out space to make it more efficient and then fit in with a biochemical bead, perfect combination。
Take the led light and save the electricity。


In order to maximize the use of space, some sizes of fish caps were measured and three-dimensional impact maps were made。

The filter is not intended to be just that simple on the lid, and i use the opening of the lid to make a part of the filter inside, and to put up some altitude as a dropspace. That way, you can use all the space to make a drop-down filter。


Because of the glass, there were no small boxes, so the water had to be diverted by several panels. Add an aclik partition to the partition so that the level is evenly spread over each grid, and the best damp separation can be achieved with rain pipes。


It's basically a structural design, but for beauty, it has to be decorated. It is intended to wrap the filter with black glass or stickers, and also to dispose of the lid。




For these wooden stickers, a treasure is sold and can be found at random. But at the end of the day it felt a little waste of space in front of the lid. So you put a little jar in front of you, so you can feed a little fish。


Filter making diagrams
White glass is painted, but it would be better to buy it directly, so there is no need to worry about bubble water。





When it's done, it runs filters, with two nitrogated bacteria。


The next morning was good, and the water was still a little bumpy。

The day-to-day feeding is maintained and the water is changed once a week for two months (one third of the bacteria is nitrified). After that, he was busy at work and did not change water for two months (two times with emc). The tigers were able to feed themselves and had recently added a white larvae. In order to test the light for 24 hours, the fish tank now has algae, with three tigers and a corrugated fish, a lobster, dozens of feed fish, a scavenger, dozens of peacocks in the tank (a year or two)。
